AWIPS Blended TPW Products

Introduction


    • This session covers the Blended TPW (total precipitable water), and Percent of Normal TPW products available in AWIPS. Although the training was developed in 2009, the principles discussed still apply. Data sources used for these blended TPW products will be identified. Also, the presentation of these products in AWIPS will be illustrated, as well as the current AWIPS display limitations. Finally, basic operational uses of blended TPW products will be identified.
    • Learning objectives:
    • Tropical cloud identifcation.
    • Identify data sources used for Blended TPW products
    • Understand presentation of products in AWIPS
    • Become aware of current AWIPS display limitations
    • Recognize basic operational uses of Blended TPW products

Training Session Options


  1. Web-based Video training session
    Note: Be sure to have your speakers on and the volume loud enough to hear the presentation.

 

ASCAT Winds

Introduction


    • This session covers the characteristics of the Advanced Scatterometer, or ASCAT, instrument aboard EUMETSAT’S MetOp-A satellite. ASCAT data became available in AWIPS with the version released in February 2009 (OB9). The coverage and biases of the ocean vector winds retrieved by ASCAT will be assessed. Also, comparisons between ASCAT data and QuikSCAT data will be made. Finally, a warning decision will be presented to illustrate effective utilization of ASCAT data for marine operations.
    • Training Topics:
    • Understand how ASCAT works.
    • Assess strengths and weaknesses of ASCAT wind retrievals.
    • Identify contrasts between between ASCAT and QuikSCAT data.
    • Understand how to best use ASCAT data operationally.

Topographically Induced Convergence Zones and Severe Weather

Introduction


This training session focuses on severe weather considerations where topography plays the key role in the production of convergence/vorticity zones. Four short case examples highlight different types of convergence zones including the Puget Sound Convergence Zone, the Denver Vorticity Convergence Zone, the Mogollan Rim Convergence Zone, and the Snake River Plain Convergence Zone.

Coastal Severe Convective Weather

Introduction


This training session focuses on severe weather considerations along coastlines…including island effects. Factors to consider along coastalines and near islands are addressed and supported by several case studies.
